[PATCH 3/4] gold/aarch64: Check non-PIC relocation for PIC output

[H.J. Lu]

Call check_non_pic on non-PIC relocations for PIC output, excluding
relocations against _GLOBAL_OFFSET_TABLE_ which is a local symbol
defined by linker.  Since aarch64 does require PIC relocations for
PIC output, set FN_PTRS_IN_SO_WITHOUT_PIC to false for aarch64.

	PR gold/19328
	* aarch64.cc (Target_aarch64::Scan::global): Call check_non_pic
	for PIC output.
	* configure.ac (FN_PTRS_IN_SO_WITHOUT_PIC): Set to false for
	aarch64.
	* configure: Regenerated.
